Assembling A Switch Stack; Cabling The Switch Stack - Dell PowerEdge M I/O Aggregator Getting Started Manual

Assembling a Switch Stack

After you complete the initial configuration, the Aggregator is powered up
and operational. Stacking is supported only on the 40GbE ports on the base
module.
Stacking is limited to two Aggregators in the same chassis in a single stack. Up
to three stacks are supported in an M1000e chassis. To configure a switch
stack, you must use the CLI.

Cabling the Switch Stack

Figure 1-9 shows a stacking example using two Aggregators in a chassis. The
Aggregators are connected to operate as a single stack in a ring topology using
only the 40GbE ports on the base modules. You can use the 40GbE ports on
the base module to create a stack in either a ring or daisy-chain topology.
Prerequisite: Before you attach the stacking cables, all Aggregators in the
stack must be powered up with the default or reconfigured settings as
described in "Reconfiguring Default Settings" on page 21.
